Study says eliminate pelvic imaging to reduce radiation for the detection of venous thromboembolism

03.05.2011
A recent study shows that pelvic imaging using computed tomography (CT) examinations are not necessary for diagnosing patients with venous thromboembolism (VTE) and eliminating this exam can significantly reduce a patient's exposure to excessive radiation dose.

CT venography of the pelvis during CT pulmonary angiography does not improve the detection of VTE, says Dr. Charbel Ishak, lead author for this study. He asserts, "Using CT venography in the lower extremities without including the pelvis can decrease the population's radiation dose generated by CT usage."

In a retrospective review of 1,527 patients at the Nassau University Medical Center during a three-year period, only 0.3% (5 of 1,527) of patients presented with isolated pelvic VTE after pulmonary embolism was ruled out of the CT protocol.

Dr. Ishak believes that these results are promising for helping radiologists implement new protocols for pelvic examination and reducing further radiation in patients. He says, "Radiologists and technologists can eliminate pelvic imaging while acquiring only images of the lower extremities with CT venography, starting from groin to below the knee. We believe that by stopping the imaging of the pelvis, we can decrease patient radiation dose without significantly affecting the diagnosis of VTE."

Dr. Ishak will deliver a presentation on this study on Tuesday, May 3, 2011 at the 2011 ARRS Annual Meeting at the Hyatt Regency Chicago.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
